Feels-like temperature calculator
See the temperature your body actually feels, with wind chill and heat index. Example: 86 °F at 80% humidity feels like about 100 °F.
Apparent temperature formula (Australian BoM). High humidity feels hotter; wind feels cooler.
How the calculation works
Feels-like temperature combines temperature, humidity and wind. In heat with high humidity sweat evaporates less, so it feels hotter; wind helps cool down.
Examples
- In heat: 33 °C with high humidity can "feel" 40 °C+.
- In cold: 5 °C with strong wind can "feel" below 0 °C.
Frequently asked questions
Why does it feel hotter with high humidity?
Because sweat evaporates more slowly, making it harder for the body to cool down.
Why does wind cool you down?
Wind removes the warm air layer next to the skin and speeds sweat evaporation, increasing heat loss.
Does feels-like change the real temperature?
No — the thermometer shows air temperature. Feels-like estimates how your body perceives it.
Why does humidity make it feel hotter?
Because the body cools mainly by evaporating sweat, and humid air blocks evaporation. At 30 °C with 80% humidity it feels close to 38 °C.
Does wind change how hot it feels?
Little on a hot dry day. Wind chill is a cold-weather formula; in heat, humidity dominates.
Does the feels-like value include sunshine?
No. The formulas assume shade; direct sun can add several degrees to what you actually feel.
